Letters Patent No. 99,242,

dazed January 25, 1870.

IMPROVEMENT IN HANDLES FOP.. KNIVES, FORKS, &c.

To a-Zl whom, it may concern:

Be it known` that we, W'ILLIAM SANDERSON and JAMES J. Dn BARRY, of New York city and county, in the State of New York, have invented certain new and useful vlmprovements in Knife, Fork, and other Handles; and lwe do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this application.

O ur invent-ion relates to certain new and useful improvements iu the method of manufacture of knife and ibrk-handles, and other handled instruments.

lrevious to our invention, various vays of forming and attaching the handles of knives, forks, and other handled instruments have been suggested and made the subject of Letters Patent, among which may be found some in which a suitable composition is moulded around the tang of the blade, and covered (in the operation between dies) with a metallic jacket, as, for instance, as shown in Letters Pat-ent granted to TIL- LIAM Sannnnsox, August 10, 1869.

Our invention has for its main objects to produce a simple, cheap, and exceedingly strong and durable handle todmives, forks, &c., a-nd to also provide a means by which such desirable handles may, at the option 0f the maimtaeturer, be made and sold separatel y from the other part of the knife, fork, or other instrument, and so that they can be readily applied to such other parts and to these ends,

Our invention consists in forming the handle of a knife or other instrumentI of some-suitable composition moulded (between dies in the usual manner) around the tang, in combination with a metallic fillet or strips to solder on, and metallic scales formed and laid over the composition and metallic fillet, and secured, all as will be hereinafter more fully explained; and

Our invention further consists in making handles of a suitable composition covered with metal, and adapted to be separately manufactured and subsequently applied to the tangs of knives, forks, &c., as will be hereinafter more fully explained; and

Our invention further consists in certain improvements in the method of forming and uniting the parts hereinafter described.

To enable those skilled in the art to make and use our invention, we will proceed to describe it more particularly, referring by let-ters tothe accompanying drawings, in which- Figure l is an elevation of a knife-blade and the false tang, such as we propose to use;

Figure 2 is a similar view, showing a modied form of false tang;

Figure 3 i's an elevation of same, after having had the composition and soldering-strip of the handle applied to it;

' Fi gurc 4 is a detail view of one of the metallic scales, or half of the metal case which covers the composition and strip, seen at'fiff. 3, and which is united on the said strip;

Figure 5 is a view of a finishedknife-handle and blade;

Figure 6 is a section of same, at the line x x;

Figure 7 is a cross-section ofthe same, at y y;

Figure S is a View, showing a modilication of the false tang;

Figure 9 is a view, showing the tang of a blade as used in connection with a false -bolster and metal-lined tang-cavity in the composition handle; and

Figure 10 shows the application of a binder or strengtliening-terrule.

The several ljgures will be more fully comprehended by references hereinafter made to them.

The same device or part is designated in the several gures in which it may be shown, by the same letter 0f reference.

In'tlie several iigures- A is the blade of au ordinary case or table-knife; and 1), the handle, all of about the usual shape and external appearance.

The blade is made with a bolster, e, and tang d, as usual, except that we propose sometimes to have the tang shorter than usual, though it may be of the usual length, as seen at iig. l.

e represents what may be designated as a false tang. It is formed after thefashion of a knife-tang, and with the bolsterfplate j', as shown at figs. 1 and 2. This tang may be made either the shape seen at de. 1, or that secu at iig. 2, or of any other proper form, and is adapted to receive in,to it a screw-threaded tang, formed on or fast to the blade A, and the plate f is adapted to tit up against the bolster c, of the blade.

g is the composition portion of the handle, which is moulded around Vt-he tang or false tang, (as the case may bc,) in dies, in the usual manuel', but which has embedded in it a flllct or strip of metal, t, which extends around, asshown, is united to the false bolster, and forms a metallic surface, on which the uniting of the edges of the metal covering may be formed perfectly, by soldering. This strip or fillet i maybe composed ot' soft metal, which will eect the soldering, by the mere application of heat, at the joint between the parts of the sheet-metal covering, and we propose to form this fillet, in the dies, with a rib or feather, as seen at 2, which is to extend up between the edges of the parts or halves of the metal jacket j, to form a perfect joint.

lhe jacket j we propose to make in two parts,as shown, which are placed or moulded over. the composition g and its fillet i, and a perfect joint formed and union of the parts effected, at' the rib 2. It will be Seen, that by placing and uniting the scales j over the Composition g, fillet t, and the bolster-plate f, .which we propose to form also of soft metal, if expedient, the several parts of the handle are securely combined together, and constitute a very solid, durable, and strong handle, the composition having a metallic core, light, and yet affording rigidity lengthwise, while the metallic jacket interlocks the whole within itself` and presents a surface capable of being .finished up as may be desired, and which will withstand heat, concussion, 85o., and it will be seen that the composition portion g, though constituting the body of the handle, is so encased that it is not exposed to the action of heat or water.

As clearly shown, the false tang and blade-tang are simply screwed together, so that the entire handleportion may be separately manufactured and sold to the trade, to be applied to blades or other instruments, to handle them.

At g. 8 we have shown a false tang and bolsterplate, in which the plate fis formed on or attached to a short tube, l, which is tapped ont so as to receive, at one end, the shank or tang 'm2, and, at the other, the tang ofthe blade A.

I n lieu of the false tang, only a bolster, '11, (such as seen at iig. 9,) may be used in connection with the composition and metal lillet, and the tang of the blade be made/of the usual length, and formed with a screwthread on it, so that after moulding the composition over it, said tang may be screwed ont for the purpose of making' other handles over it, or to repair or replace the blade, but, in suoli mode of manufacture, we propose to wrapI the tang with a covering of thin sheetmetal, properly prepared, before moulding the handle, so that a metallic screw-thread surface will he formed in the handle, the sheet-metal adhering to the compo sition. f

II" deemed expedient, the bolster-plate, composition, fillet, and jacket, may be formed with a depression or shoulder, as seen at tig. 10, for the accommodation of a band or ferrule, s, which may be placed tight over the end of the handle before its attachment to the blade, and, by this arrangement, the handle may be made more secure, in the combination or union of its several parts.

It will be understood that the composition and metal `of a blade of any instrument, is apparent, and it'will be seen, that byforming the fillet of softmetal, or selfsoldering, and with a rib or feather, 2, as explained, a quick, cheap, and perfect uniting of the parts may be effected, and a smooth joint presented for plating and finishing up, which are great desiderata.

Ne do not Wish to be understood as claiming the mere combination of a composition core or body, -withI a metal'covering, as that is shown in the patent of SANDnRsoN, before referred to.; but

Having fully explained our invention,

fha-t we claim as new, and desire to secure by Letters Patent, is-

Forming handles of knives and other instruments,

Aof any suitable composition, moulded over a metallic core, (adapted to receive the tang of the instrnment,) and covered with a metallic jacket, all substantially as described.

Also, a handle, made substantially as described, and adapted to be manufactured and applied to various instruments.

Also, the peculiar manner of forming a perfect joint in the metallic cover, by a rib or feather raised on the soldering-stri p, substantially as described.

Also, forming the handle with a depression, and combining with the bolster-plate, filling, and jacket, a binder or strengthening band, s, substantially as and for the purposes set forth.-

ln testimony whereof, we have hereto setour hands and seals, this 7th clay ot'Decem-bcr, 1869.
